Homemade kombucha typically takes 7 to 14 days to ferment, depending on temperature and taste preference.

Estimated Duration: 7 days

Fermenting homemade kombucha involves two stages: primary fermentation (7-14 days) and optional secondary fermentation (2-5 days for carbonation). The duration depends on factors like room temperature (ideal: 75-85°F), sweetness preference, and desired tartness. During primary fermentation, the SCOBY (symbiotic culture of bacteria and yeast) converts sweet tea into kombucha. Taste-testing after 7 days helps determine readiness—longer fermentation yields a tangier, less sweet brew. Secondary fermentation in airtight bottles with added flavors (fruit, herbs) enhances carbonation. Proper sterilization, quality ingredients, and monitoring prevent mold. Store in a dark, well-ventilated space and avoid metal containers. Regular brewing improves consistency and flavor.
